Railway track design ppt 2018. Vertical alignment defines the elevation of the low rail of each track. There are two standard methods prevalent for designing a turnout.

These are the (a) coles method and the (b) irs method.
It’s the most important part of railroad construction.
Railway frog, or railway crossing, is a section of steel rail crossing point of 2 rail tracks, a frog is the built up pieces of trackwork that allow 1 rail to cross another with an opening for the wheel flange, found on turnouts and diamonds were 1 rail intersects another, rail frog can be cast as 1 piece or fabricated with 2 or more number of rail tracks,. Pair of points and a crossing, to divert a train. The tracks may be parallel to, diverging from, or converging with each other. A railroad switch is a collective of devices working together enabling wheels running from one railroad track to another.
The switch points are the section of the switch that moves.
The working group mainly includes stock rails, switch points, closure rails, frogs, guard rails and other connecting parts. They are tapered on most switches, but on stub switches they have square ends. Fitting a curved point, a double slip and some super elevated track.patreon link.

In ordinary conversation, it is common to use the word “switch” when referring to a “turnout,” which is technically incorrect.
A seminar presentation civilengineering 2018 rajasthaninstituteof engineeringandtechnology jaipur submittedto: Agico offers the steel grades for railroad rails with a tensile strength range of 690 (min) to 1179 (min) n/mm 2. There are two types of rail track points: Points (switch rails or point blades) are the movable rails which guide the wheels towards either the straight or the diverging track.

If the train is diverted to the right of the main track in. The passing points of shipping in a channel gave the current day points (or turnouts) their name [1]. If the train is diverted to the left of the main track in the facing direction.
The important terms used in describing the design of turnouts are defined as follows.
Left, where the additional track appears on the left side of the main track right, where the additional track appears on the right side of the main track The simplest arrangement of points and crossing can be found on a turnout taking off from a straight track. Railroad tracks are often referred to as railway tracks or railroad rail. They are tapered on most switches, but on stub switches they have square ends.
Wide to gauge catch points.
Points (switch rails or point blades) are the movable rails which guide the wheels towards either the straight or the diverging track. Vertical grades each straight grade shall be defined by a pair of terminal points called intersection points (ip), which shall preferably be located at whole 20m kilometrage points. These are the points which govern the alignment of a railway track. One point is basically consists of single pair of tongue rails and stock rails with various necessary fittings.
These methods are described in detail in the following sections.
Railway frog parts and types. As early as the 18th century, turnouts were used in the first mine railways in england. The point & crossings are used in the railway tracks to guide the trains for directional changes. The busy traffic on the railway resulted in.
Points and crossings are provided to help transfer railway vehicles from one track to another.
This point & crossings is comprised of three prime components, namely point, lead and crossing element. Points and crossings are necessary because the wheels of railway vehicles are provided with inside flanges and, therefore, they require this special arrangement in order to navigate their way on the rails. They enabled trains to switch between different tracks without interruption of the journey. Tyred train technology available at the rubber tyred metro website.
Trap points are found at the exit from a siding or where a secondary track joins a main line.
Sometimes a track is located between two other tracks that are converging, and there is.
